JOSEPH VOLZ, OF ELLIOTT, NORTH, DAKOTA.

FANNING-MILL.

Application filed May 6, 1914. Serial No. 836,769.

To all whom it may concern Beit known that LJosnPn VoLz, a subject of the Czar of Russia, residing at Elliott, in the county of Ransom and State of North Dakota, have invented new and useful Improvements in Fanning-Mills, of which the following is a specification.

This invention relates to fanning mills for cleaning and separating grain, and it has forits object to produce a machine of this class which will be simple in construction and efficient in operation.

A further object of the invention is to produce a fanning mill including a spout through which the grain is conducted by gravity to the shaking shoe, and means for feeding the grain from the source of supply to said spout whereby the relatively light and heavy grades of grain will have an op' portunity of being separated as it drops by gravity before it is discharged on to the shaking shoe. 7

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise details of construction therein exhibited, but that changes alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings,-Figure 1 is. a sectiona elevation of a fanning mill constructed in accordance with the invention. Fig. 2 is a view in side elevation showing the opposite side of the mill.

Corresponding parts in both figures of the drawing are denoted by like characters of reference.

The frame 15 of the improved mill which is of conventional construction supports a feed hopper 16 which may be equipped with the customary regulating slide 17 to regulate the discharge of the contents of said hopper on to a slatted endless conveyer 18 which is trained over shafts 19, 20, said shafts being located in different horizontal planes so that the conveyer or elevator will be supported in an inclined position.

21 is a driving wheel which is connected by a chain or link belt 22 with a sprocket wheel 23 on the shaft 24 of a blast fan 25 which is supported for rotation in acasing V or a hous ing 26 having a downwardly extending discharge spout 27. Motion may be transm1tted from the fan shaft 24 to one of the elevator supporting shafts 19 by means,

of a chain or belt 28.

The elevator l8' is arranged to discharge 34 of a shaking shoe 35 which is supported.

in the customary manner by means of links 36, one of which has an upwardly extending arm 37 connected by a pitman 38 with a wrist pin 39 on the sprocket wheel 23 of the fan shaft. The shaking shoe has a side outlet 40. 4

In the operation of this invention the grain is deposited from the hopper 16 onto the lower end of the elevator 18 0n which it is spread in a thin sheet or layer, and whereby it is carried upwardly to the duct 29. In sliding downwardly over said duct theheavy grains, by reason of their greater gravity,

will acquire greater speed and impetus than the lighter grains, and in passing over the dlscharge end of the duct such heavy grains, impelled by the impetus acquired, will jump over the space between the discharge end of the duct and the contiguous edge of the valve 31 and will alight on the latter, being thereby conveyed to the sieves of the shaking shoe. Any of the heavy grains will be prevented by the housing 30 from jumping clear of the shaking shoe and being lost. This action will take place irrespective of the blast from the fan which must obviously be regulated or moderated in such fashion, as not to force the heavy grain downwardly through the space between the fan and the duct. The lighter grains, however, which havenot acquired sufiicient m0- mentum, will be deflected downwardly between the valve and the duct, this action being assisted by the blast from the fan. In this manner a very considerable portion of the light and undesirable grain including wild oats, garlic and other wild seeds will be separated from the wheat before it reaches the sieves of the shaking shoe Where the separation is completed. It is obvious that by proper adjustment of the valve 30 the intervening space between the valve and the discharge end of the duct 29 may be varied to obtain the best conditions for successful operation. It is also evident that the housing 30 is in no wise connected with the shaking shoe so that the operation of the latter will not be obstructed.

I have found that by separating the wild seeds from the wheat gravitationally in the manner described, the cleaning operation may be performed more rapidly, thoroughly and with greater ease than heretofore.

Having thus described the invention, what is claimed as new, is

1. In a fanning mill, a hopper, an inclined duct, means for transferring grain from the hopper to the upper end of the duct, and a deflecting valve supported adjacent to and spaced from the discharge end of the duct to effect separation of the lighter from the heavier grades of grain, the heavier grades acquiring in transit over the duct suflicientmomentum to jump over the space between the valve and the discharge end of the duct.

2. In a fanning mill, a hopper, an inclined duct, means for transferring grain from the hopper to the upper end of the duct, and a deflecting valve supported adj acent to and spaced from the discharge end of the duct to effect separation of the lighter from the heavier grades of grain, the heavier grades acquiring in transit over the duct sufiicientmomentum to jump over the space between the valve and the discharge end of the duct, and means for adjusting the valve to vary the space between the said valve and the discharge end of the duct.

3. In a fanning mill, a hopper having a gate, an inclined duct, an elevator to convey grain from the hopper to the upper end of the duct, a valve spaced from the discharge end of the duct, and means for adjusting the valve to vary the intervening space.

v 4:. In a fanning mill, a hopper having a gate, an inclined duct, an elevator to convey grain from the hopper to the upper end of the duct, a valve spaced from the discharge end of the duct, means for adjusting the valve to vary the intervening space, and means for discharging a blast of air downwardly through the intervening space between the valve and the discharge end of the duct.

5. In a fanning mill, a hopper having a gate, an inclined arcuate duct, an elevator to transfer grain from the hopper to the upper end of the duct, a shaking shoe supported beneath the discharge end of the duct, a valve supported in proximity to the discharge end of the duct to guide grain that jumps over the intervening space to the shaking shoe, and a housing in which said valve is mounted.

6. In a fanning mill, a hopper having a gate, an inclined arcuate duct, an elevator to transfer grain from the hopper to the upper end of the duct, a shaking shoe supported beneath the discharge end of the duct, a valve supported in proximity to the discharge end of the duct to guide grain that jumps over the intervening space to the shaking shoe, a housing in which said valve is mounted, and means for discharging a blast of air downwardly through the intervening space between the valve and the discharge end of the duct.

In testimony whereof I affix my signature in presence of two witnesses.
